Used as a biocide in industrial water treatment systems to control microbial growth, particularly in cooling towers and paper mill systems. It is effective against bacteria, fungi, and algae due to its ability to disrupt cell membranes and inhibit enzyme activity. Also employed as a preservative in wood protection and in some coating formulations to prevent microbial degradation. Its lipophilic nature enhances penetration into biofilms, making it effective in hard-to-treat environments.
